Does drinking more water help erectile dysfunction

Can dehydration cause erectile dysfunction? Knowing the answer to this question may help with preventing ED.

Erectile dysfunction (ED) can occur at any age. While circulatory problems and age often play a role, there are lots of other overlooked factors to be aware of.

Quick FAQs

Dehydration can cause erectile dysfunction because it limits the oxygen and blood flow that the penis needs to get an erection.

Drinking water can cause an increase of blood circulation in the body, which can help men with erectile dysfunction stay aroused.

Other cause of erectile dysfunction include mental health issues, high blood pressure, and obesity.

Diet, exercise, and even hydration can impact erectile health. It’s important to know the correlation between dehydration and ED to help yourself have stronger erections.

Can Dehydration Cause Erectile Dysfunction?

Dehydration can contribute to erectile dysfunction because it limits the blood flow and oxygen that the penis needs to have an erection. If blood flow becomes permanently reduced, the penis becomes less sensitive.

Doctor's Insight: VitaFLUX Nitric Oxide Booster is designed to help increase blood flow by boosting your nitric oxide production.

A lack of penile sensitivity makes it even more difficult for a man to achieve an erection. Staying properly hydrated helps the penis get the blood and oxygen necessary to maintain good erectile health.

So does dehydration affect erectile dysfunction? Yes, it can affect not only your sexual health but your overall well-being.

Does Drinking Water Help Erectile Dysfunction?

Drinking water causes more blood to circulate in the body, which may help men with erectile dysfunction to stay aroused.

Fixing ED is often a case of trial and error. Sometimes hydration is the key, while other times it may require treatment for high blood pressure, pills specifically for ED, or other available options.

However, drinking more water and staying hydrated is one of the simplest things anyone can try to see if it helps.

Signs of Dehydration

There are some signs of dehydration that can indicate it’s time to drink more water. Among the most common symptoms of dehydration include:

  • Headache
  • Dizziness
  • Dry mouth
  • Darker colored urine
  • Infrequent urination
  • Fatigue
  • Anxiety
  • Anger

Drinking water will certainly help prevent these symptoms from getting worse. But an over-the-counter pain reliever may be necessary to help clear symptoms like headaches once they appear. 

Drinking electrolytes (such as potassium and magnesium) can also aid in symptom relief. It doesn’t matter if it’s from popular sports drink brands or from natural sources like coconut water.

Dehydration can become a serious medical emergency if it’s severe or long-lasting. Those with conditions like diabetes and high blood pressure may be more prone to complications as well.

Some signs of severe dehydration include:

  • Confusion
  • Muscle cramps
  • Urinary tract infections
  • Kidney stones
  • Kidney failure
  • Seizures

If you experience any signs of severe dehydration, call 911 or visit the emergency room immediately.

How to Prevent Dehydration

While drinking plenty of water a day can help increase hydration, there are a variety of other ways it can be increased.

Add some electrolytes like potassium, sodium, chloride, and magnesium into your diet for increased hydration. Some popular methods include:

  • Sports drinks (without sugar)
  • Dissolvable tablets for your water bottle
  • Natural sources like coconut water and bananas
  • Multivitamins

Other Causes of Erectile Dysfunction

Staying hydrated doesn’t cure all causes of ED, and unfortunately, there are a lot of potential causes.

Many of these causes are often intertwined, such as dehydration and high blood pressure, but the treatments may be vastly different depending on the individual.

Some of the most common causes of ED in men include:

  • High blood pressure
  • Dehydration
  • Obesity
  • Diabetes
  • Prescription medications
  • Heart disease
  • Circulatory problems
  • Tobacco
    • Alcohol
    • Substance abuse
    • Insomnia
    • Anxiety
    • Sexual trauma
    • Mental health issues

      While this list may seem long, there are many treatments available for ED that can be helpful. Look into different options such as increasing hydration or taking ED medication.

      Tips for Erectile Health

      Erection health is often tied directly to overall physical health and sometimes to mental health as well.

      In regards to physical health, the best things that can be done to maintain or improve erection quality include:

      • Maintaining a healthy weight
      • Exercising daily
      • Eating a well-rounded diet
      • Avoiding or minimizing alcohol and tobacco
      • Maintaining blood pressure

      Consider also taking a supplement like VitaFLUX Nitric Oxide Booster, which is clinically proven to increase erectile functioning.

      Even if a man is physically healthy, sometimes ED can occur from anxiety and other mental health issues. These issues may include:

      • Sexual trauma
      • PTSD
      • Insomnia
      • Depression
      • Anhedonia (a loss of pleasure)

      If you’re suffering from any mental health issues, speaking with a licensed therapist may be a great first step in addressing the issue and working towards a healthier future.


      Dehydration is an often overlooked cause of ED that should be given more attention.

      Proper hydration can help with maintaining proper blood flow throughout the body. As a result, the penis gets the necessary level of blood for continued penile sensitivity and maintaining an erection

      Make sure to drink enough water in a day and add more electrolytes into your diet through vitamins, coconut water, or by eating a well-rounded diet.

      Staying hydrated is one of the easiest things that can be done at home, and it’s worth trying to see if it helps with ED. If you still experience erectile dysfunction, consider speaking with a doctor about taking sildenafil (Viagra) or tadalafil (Cialis).
